taken on the line 3-3 of Figure 1; and

. Figure 4; is a view similar to ,Figure 3 taken on theline of Figure1.v

Similar reference numerals in all of the figures of the drawingdesignate like parts.

Referring to the drawing, it will be seen that the improved windowcomprisesan upper pane 1 0, and a lower pane 11, fthe upper Apane beingpreferably xed in position in any suitable manner and having its loweredge supported upon a filling strip 12, in-

serted in a recess 13 formed 1n the sides of the window frame 14, whichyis preferably -constructed of concrete and precast prior to v itsmounting within the walls of the buildmg. l

The lower pane 11 is mounted vto slide freely up and downto variouspositions, andits vertical edges engage the free ends of spring-guidemembers secured in position within the recesses ,13 at both sides of thewindow and extending approximately the full length'of the window andpreferabl constructed of spring-brass material. Eac 40 of thespring-guide members is constructed of sheet-metal and is bent to formlegs 16 and 17 arranged at right-angles with re'- of the frame bysuitable fastening means 19,

and its free end 'is bent backwardly and spaced from the main portion ofthe/'leg to form a spring-tongue 20 adapted to frictionally engage theadjacent vertical edge of l the lower pane.

Figure 3 1s a transverse sectional view y Pane 11 is also frictionallyheld in place against the spring-guides 18 byl suitable pads 21,(preferably formed of felt), secured to the rear faces of thewindow-frame stops 22, each stop preferably having its rear face formedwith a portion 23 adapted tolie'approximately parallel to the panes anda remaining portion 24 inclined from said parallel ortion 23 to providea widened space forming part of the reces:J -13 and into whichy isadapted to extend the leg 17 of the spring guide. The felt pads21 haveone end secured to said parallel portions of the stops 22, and are bentbackwardly over said secured ends on the parallel portions, and theneach has its other end secured to the said inclined portion of the stop.

Stops 22 are preferably formed of concrete and precast before assembly,as is the frames or 'ambs heretofore described.

- n the sill of the window, also preferably 1,695,903V APATENT OFFICE;

formed of concrete, is formed a groove 25 irri," f

which is located a sill-pad 26 of felt, against.

and upon which the lower edge of the lower pane 11 contacts and restswhen said lower pane 1s down or 1n 1ts closed pos1t1on, and

at the top of the window is arranged a pad 27 lfixedto a horizontal stopmember 28 and ladapted to extend across the path of the lower pane andengage the front faceofthe upper pane adjacent to its upper ed e.

It is understood that themvertical remova le stops 22 and the horizontalstop 28 can be cast together as a unit, or separately, as

desired.

Lower pane 11 is preferably provided with a knob or knobs 2 9 adjacentto its lower edge with which the .pane can be vraised or lowered asdesired, These knobs ca n be secured to the glass in any suitablemanner, preferably by cement. y E i I' To assemblel the arts of thewindow, the upper pane is first xed in position upon the filler strips12, then .the spring-guides are placed and fixed in-position with theirguidlng legs 16 bearin at against the surface.

dow-sill, all danger of breakage by contraction or jarring iseliminated.

3 These windows-are'especially adapted for use in fire-proofconstructions having precast jambs and window-stops, and more especiallyIin all windows of standard narrow designs where an overweight of theglass will not be an objection.

ltheupper pane is shown of less length than the lower pane, and the'upward movement of the lower .pane is limited bythe upper ad 27, but itis understood, that if desired, t e upper edge of .the lower pane caribemade to slide into a pocket at the top side of the window.

If necessary, especially where a heavy sliding paneis used, window lockscan be used at the sides thereof to hold the same in adjusted positions.

The special formation shown of the spring-guides is essential, in that`the springpane vstationary at any raised position desired,

tongue is unhampered, and its .angular shape and folded front edge makethe remaining part substantially rigid.

Having fully described the invention, what is claimed, is:

. 1. In a window construction for concrete structures, an upper sashlesspane fixed in position against movement, a lower sashless pane whichextends into recesses at the sides of the window frame, a guide at eachside ofthe window extending continuously the full height thereof andprovided with a leg adapted to engageone face of the upper pane andpress it against an abutment of the precast frame and said leg beingalso provided with a spring-tongue adapted to en-v I gage the fulllength-of the adjacent vertical `edge of the lower pane at all times,and" precast side stops having Iiexible pads for engaging the face ofthe lower pane adjacent its vertical edges to ret-ain lthe same inposition.

2.
